Application filed October 19, 1920. Serial No. 417,952.

To all whom it may concern.

Be it known that I, FREDERICK JAMES.

THODY, a subject of the King of Great Britain, a resident of the town of Swift Cur rent, Province of Saskatchewan, Dominion of Canada, have invented certain new and useful Improvements in Sheaf Shockers, of which the following is a specification.

This invention relates to improvements in sheaf shocker-s of theftype in which the" sheaves are received from the binder" deck:

by a suitable transferring member which deposits them in a shock forming member, which 1s caused at suitable intervals to form the shock and deposit it upon the ground,

and the general object of the invention is to provide a device of the character in which the desired operation may be efficiently carried out.

Other objects of the invention are to provide an effective device of this character, by which the shock may be formed from the discharged sheaves and deposited upon the ground in proper upright position and compressed together to form a stable shock.

Further general objects are to co-ordinate the functions required of the'va'rious parts in such a way that the sheaves will be received from the binder, transferred and de'-' posited as a shock without interruption through mechanical difiiculties or the like. Particular objects of the invention relate to the transferring member and to the me chanism by which it is caused to receive the sheaves and deposit them in the sheaf shocking member.

Other. particular objects of the lnvention relate tothe mechanism for supporting and operating the shock forming member, and l have for their object the proper compress-ion of the sheaves, the lowering of the shock forming member in a substantially vertical position, the moving of the shock forming member rearwardly as it is depositing a shock, and gradually raising the shock forming member to return it to normal position.

Other objects of the invention will appearas the specification proceeds.

The invention comprises the improved construction, combination and arrangement of parts hereinafter described in detail in the accompanying specification and drawmgs. c 'In the drawings: 5

Like ch'aracters of reference indicate like parts in all the figures.

Referring to the drawings; A represents a binder of any well known construction and B the binder deck thereof, including the usual pivoted arm 10 which temporarily holds the grain priorto its discharge in the form of a sheaf. The arm '10 is turned in accordance with the usual qnech-anisin of the binder about a transverselyextending rod 11.

C indicates the frame carrying the shocking "mechanism and which 'may be of any convenient construction to support theworking part being connected at. one side to the binder frame and supported at the other side by a wheel D.

In tllGQil'lbOCllD'iGDt illustrated the connection with the binder frame i'sqnade by means ofdia-gonally extending cross bars 12 and 13, the projecting extremities of which have hinged. connection with the fran'i'e of the binder.

It is'olrrious however, that themechanism might be attached tothebinder frame in a variety o f ways,'or might be mounted independently on 'WlrtClS of its own.

E indicates the transferring ='mem-b'er by which the individual sheaves are transferred to the shock forming member F.

The transferring member E includes a basket 1 1, thre edge of which is normally "adjacent to-the'edgeof-the binder deck-and adapted to receive sheaves as they are-dis charged therefrom.

The basket is mounted with freedom to turn about an axis somewhat inclined to the horizontal, whereby when swung upwardly 'fro'm-its normal position-it will'ul-timately dumpor discharge its-sheaves into the sh'ock forming member. This is -acc0mplished by providing a supporting pivot position by means of suitable pivotally mounted retaining fingers 20 which project from a rod 21 extending longitudinally of the basket and are ]()L1111Lll6(1 in suitable bearing projections formed on a cross bar which connects the arms 15% and 19 of the bracket 17. The fingers are retained in normal position by a toggle mechanism including rods a3 and 21 suitably pivoted together, the extremity of therod 28 being pivoted to one of the fingers 20, while the extremity of the'arm 24: is formed with an eye which embraces and pivot-ally supports the arm from the pin or trunnion 15.

The normal position of the arms 23 and elis, as shown in Figure 3, where they are slightly inclined to "each other and rest against an abutment 9.5 on the bracket '17.

When thetransferring member is swung upwardly :to the po n shown in dotted lines in Figure 3, the joint of the toggle arms and 2-1 is designed to be engaged by a tappet projection 26 on the frame member 16, which will swing the pivot point of the toggle arms away from the abutment 25, thereby permitting the arms to swing together and'releasing the fingers so that the swinging fingers may swing downwardly to release the sheaf which is in the basket 14.

Qnthe return movement of the transferring'member a spring is designed to return the toggle arms 23' and 2-1: to their original position.

The transferring member as well as the shock forming member are operated from a ly cit-ending power shaft G driven ry convenient way, and is in the embodi ment illustrated pr ritled with a sprocket 28 connected by a chai to the cone spending sprocket 31) can. ,.l by the wheel 1).

The transferring member is operated from a'toothed disc or ratchet wheel gear 31 on the power shaft, which is intermittently con nccted to thc transferring member by the mechanism to be presently described. (See Figures 13, 14 and This mechanism includes an arm 32 looscl and'pivotally iounted on the shaft \1 ant carryinga ratchet 33, the ratchet being i the form of an -l.-sl aped arm having one portion journalled inthe arm 32 and havrexten'diugct'rom one side thereof to a bracket shaped end 38 of a trip dog 39, which is pivotally mounted on the arm 32 and 1s provided with a fiat spring 40 extending'from a bracket 4.1 on the arm 32 and designed to hold the l'iook-shaped end of the dog 39 in engagement with the end of the dog 35. The dogs when in this relative position hold the ratchet 33 out of engagement with the disc 31. The dog 39 is designed to be tripped at intervals by the laterally turned end 42 on a longitudinal slidable rod 43, which has the remote end formed with a hook 44 adapted to be engaged by the laterally turned end 45 on the vertically extending rod 46 suitably j'ournalied in the frame and having a laterally turned lower end 47 pivotally connected to a rod 48, which rod is pivotally connected. to a crank 49, the projecting end '50 of which is designed to be engaged by a projecting arm 51 secured to the rod 11, and

moving with the arm 10 already referred to.

A spring 52 is pr vided, holding the rod 46 in normal position and in which the end I 45 is engaged with the end 44holding the rod 43 in such position that the dogs 35 and 39 will be tripped. V v

A spring 53 extends between therod 43 and the member 16 of the frame, normally holding the rod in position with the end 42 bearing against an abutment projection 54.

The hook-shaped end 44 on the rod 43 is supported on a spring section 55which is welded or otherwise secured to the rod, or the rod itself is sufficiently thin at the end to be flexible, and the extreme end is providedfwith a tapered and'laterally curved cam portion 56 designed to bear against the side of an eye 57 formed on a rod 58 pivotally mounted'in the member 16, the lower end of the rod being formed with a turned end 59 which is held'by a spring 60 against a laterally turned end 61 of a transversely extending rod 62, the opposite end of which is provided with a crank-shaped end 63 designed to be engaged and moved by a portion of the operating mechanism for the shock 1 forming mechanism in the manner hereinafter described.

To give additional support to the arm'32, a bracket 64 may be provided secured to the side of the arm and embracing the shaft Gf The arm 32 is pivotally connected at its ex tremity to one end of a rod 65. and the op posite end of the -rod 65 is pivotally connected to the upper end of a rod 66, the op posite end of which is pivotally connected to the bracket arm 66*at a distance away from the pivot point thereof. In normal position the rods 65 and 66 extend at an acute angle to each other, being held in this position by means of an abutment member 67 of inverted ll-shape connected at its lower extremity to an arm 67 of the bracket 17 and having its 1 upper extremity curved and extending suhstai'itially at its pivotal point between the members and 66. "In this Way, when a pull is exerted on the member 65, the member 67 will support" the member 66 and cause the basket to be swung upwardly, finally as the revo ution of the basket continues, the member 66 will swing outof engagement with the member 67 and thus permit a greater movement of the basket than would be possible if the member 65 were directly pivoted to the member 67 In order to start the transferring member E on its return movement after a sheaf has been discharged, I provide a spring abutment member 68 (see Figure 6) which in cludes a cylinder 69 having a projecting plunger 70, the end of which plunger is de signed at its. extreme movement to engage an abutment project-ion 71, and this return movement is also assisted by gravity, too rapid a movement bein g prevented by means of'a spring 72, which has one end connected to the member 16 and has the opposite end connected to a link 73, which ispivotally connected to an arm 7 4 on the bracket 17.

The operation of the trip device for the transferring member. E above described is substantially as follows:

'Upon discharge of a sheaf from the bindenthe movement of the arm 10 in the automatic operation of the binder will'move the arm 51, permitting the crank 50 to swing under action of the spring 52, which carries the rod '48 which turns the rod 46 about its vertical axis, and this, through the turned end 45 moves the rod 43 longitudinally and the turned and 42 of the last mentioned rod will engage the dog 33' swinging it about its pivotal point to release the dog 35, which under action of the spring 36 will move the ratchet 33 into engagement with the disc 31, thus causing the arm 32 to travel with the disc 31; the disc has previously been'con tinuously rotating under the power derived from the wheel D through the power shaft G, The spring 52 also serves to restore the arm 46 to normal position.

The motion of the arm 32 through the rod 65 will swing the basket up towards raised position as indicated in dotted lines in. Figure 3, the sheaf being released in this raised position and discharged into the shock it back into engagement with the hookshaped end 38 releasing the ratchet 33 from the disc 31 and arresting the movement of the arm 32 permitting the has et freely to return to normal position under the action of the spring plurger and gravity already explained At the same time the spring 52 will return the rod 46 to normal position.

This excess motion is taken care of by the tapered cam portion c6 of the rod 413, which bears against the projection 57 swinging the end laterally out of engagen'ient with the end 1 5 enabling the end to swing through a wider arc than would be necessary to move the rod 13 to release the dogs. 0n the return movement of the end 45 it will slip past the projecting hook-shaped end and come into engagement with the notched portion thereof, assuming the position shown in Figure 13 of the drawings.

To assist the holding of the basket 14- in normal position, a spring catch 76 is provided having a pair of fingers 77 and 7 8 designed to resiliently engage a projection 79 on the arm 18.

The shock "forming member of the basket 13 includes a cradle H having pintles 80 and 81 journalled in suitable bearings 82 and 83 on arms 8 1 and 85 extending from one end of the main supporting lever T for the shock forming mechanism.

This main supporting lever, (see Figures 9, 10, 11 and 12), is supported at the end remote from the shock forming member by a roller 86, which runs in a guide-way 87 having an upper track 88 and a lower track 89. The roller is connected to the lever I by a shackle 90 pivotally connected to the pivot pin 91 of the roller on the lower end, and having its upper end embracing the U- shaped bale 92 connected to the extremity of the lever. The opposite end of the lever I to that which is supported by the roller 86, is supported by a pivoted bale or lever 93 of in verted U-shape, the upper extremity of the lever being embraced by a shackle 94 having a transverse pin 95 extending therethrough on which a bracket 96 is pivotally mounted having its opposite extremity embracing the end of the lever I.

It will be seen that by the provision of this pivot pin 95, as well as by the pivoting of the shackle 94;, the lever I is free to swing about these pivots under the action of gravity and so support the cradle in a horizontal position and thus deposit the shock in the position which will insure its maximum stability.

The lower extremity of the bale 93 is pivotally connected to a similarly shaped bale or lever 97, the upper extremity of which is supported from a bearing 98 connected to a cross bar 99 on the frame 0.

The lower pivoted points of the bales 93 and 97 are normally retained in fixed posinalled in a bearing 113 on the frame, the up per extremity of the bell crank being designed to be engaged and operated by a cam J as hereinafter described.

The crank 109 is retained in normal position by means of a flat spring 11a (see Figure 12), the spring being supported from a cross bar 115 on the frame.

The cradle H carries the shock forming basket which comprises a plurality ofhinged sections 116, 117, 118, 119 and 120, the sections 116, 117 being pivoted together at the rear end by the pivot pin 121, the section 118 being hinged to the section 116, the section 119 being hinged to the section 117, while the section 120 is hinged to the section 116 and designed to overlap the section 117 to avoid any opening in the bottom of the basket when open.

The sections 116, 117, 118, 119' and 120 are all supported from supporting links 122 and 123 rigidly connected to the sections 118 and 119 at one end and at the other to rods 124 and 125 on the cradle H. The position of the supporting links 122 and 123 are controlled by means of rods 126 and 127 pivoted at their upper extremities to cross rods 128 and 129 on the links 122 and 123 and pivoted together at their lower extremities. One of the rods is extended beyond the lower pivot point to form a connecting eye 130 which connecting eye, when in raised position, is supported by a pivoted hook 131 gravity and spring held in engaged position and adapted to be released by a cord or chain 132 leading to the drivers seat on the binder.

It is obvious that the eye 130 might be formed separately if desired, and connected to the pivoting point of the rods.

It will be seen that when the pivoted hook or lever 131 is swung to released position the parts 116 and 117, 118, 119 and 120 are closed together under gravity brought about principally by weight of the sections 116 and 117, the inner sections being forced inwardly as they move downwardly by the links 122 and 123. The link 123 carries a hook-shaped projection 133, and as the section 119 is swung inwardly the projection 133 will engage with the crank shaped end 134 on a longitudinally extending rod 135 journalled in suitable bearings 136 and 137 on the arm 84 as shown in Figures 5, 16 and 27.

The opposite end of the rod 135 is formed with a crank 138 connected'by a link 139 with a bell crank 1410 mounted in a bearing 141 on the member 84, the opposite projecting end 142 of the bell crank lever being adapted to engage a laterally turned end 143 end to the dog and at the other end to the sleeve which spring is adapted to return the rod to its normal position.

The rod 151 projects rearwardly and is pivotally connected to a bracket 154 onthe cradle H and it is impossible for the cradle to be turned on its transverse pivot until the end 149 of the dog is swung away from the end of the sleeve 150, but when the dog is swung away from the end of the sleeve,

the rod 151 may slide rearwardly permitting the cradle to turn on its pivot swinging the basket to vertical and discharging position.

The sleeve 150 is pivotally supported from a bracket 155 on a cross bar 156 of the frame, the bracket being pivotally connected to a corresponding bracket 157 which encircles the sleeve. 1

It will be noticed that the sleeve 150 is (see Figs. 2, 16, 17 and 18) of considerable length which permits the end of the rod 151 to run backwardly in it as hereinafter described,

To return the end 142 to normal position, a spiral spring 135 is provided on a tie rod 135 extending between the rod and the hearing 137 and secured to'each.

The turning movement of the cradle and basket to dumping position is assisted by means of tensioned springs 158 extending from lugs 160 on the cradle to levers 161 on the projecting ends of pintles 82 and 83.

The cradle H carries a tappet -arm 163, which tappet arm is adapted as the cradle swings, to engage a laterally turned end 164 on a longitudinally extending rod 165 suitably journalled in the frame and having a laterally turned projecting inner end 166 as shown in Figs. 5 and 19. This laterally turned end 166 is connected by a link 167' with a centrally fulcrumed dog 168 mounted on afixed standard 169 on the frame, the

dog 168 normally holding a pawl 170 in disengaged position, this pawl being pivotally mounted on an arm 171 connected rigidly to a sleeve 172 which is loosely and pivotally mounted on the power shaft. The pawl 170 carries a roller 173 designed to engage one of a series of semi-circular recesses 174, which form teeth in the periphcry of a disc or ratchet wheell7 5 mounted and turning with the power shaft G. The sleeve 172 also carries the operating cam J.

When the pawl 170 is moved intoengagement with the teeth on the ratchet wheel17 5, the arm 171 moves with it turning the cam J, which controls the movement of the roller 176 supported on a swinging arm 177, which arm is pivoted at its lower extremity to the frame. 7

The swinging arm 177 is pivotally connected to a rod 179 which extends rearward-' ly and is pivotally connected at its rearmost end to the shackle 94 at the top of the lever 93 connected to the lever I.

The first action of the cam is to permit the roller to drop inwardly on the radially'extending portion 180 of the cam, the remaining'travel'of the cam being-operative to hold the basket in position and then to gradually raise the cradleand basket and return them to normal position. 7

The cam carries on one side, a roller 181 and as the cam turns, this roller will engage between the forked ends 182 of a rod 183, the opposite end of which is pivotally connected to a bracket 184 on the bale or lever 97.

The cam J carries a second roller 185 on the opposite side to the roller 181 designed at a certain point of revolution to engage a cam surface 186 on a lever 187, which lever is pivoted toa second lever 188, the lower extremity of which is suitably journalled on the frame, and has an arm 189 which is connected by a tension spring 190 with the pivoted arm 177.

It will be seen that the lever 187 is free to both move on its pivotal point and to move rearwardly. The rearmost end of the lever 187 is pivotally connected to a rod191 journalled in a suitable bearing 192 supported from the lever I, and its forward end is provided with a pulley 193 or other contact means designed to engage the outer surface of the connecting eye 130 to cause the openin of the basket through the arms 126 and 12 I To prevent the sheaves from falling out of the end of the basket until the proper position is reached, end doors 195 and 196 are provided supported by U-shaped bales 197 and 198, the extremities of which are pivotally mounted in projecting arms 199 extending'from the arms 84-and 85. These 'doors are caused to swing outwardly and upwardly at the proper moment by curved bales 200 and 201 pivotally connected to the doors and having theiropposite extremities connected by swivel or universal joints 202 to projectformed thereon which fits through and turns in a suitable perforation in the bracket 203.

The operation of the shock forming mechanism is briefly as follows:

WVhen a sufficient number of sheaves have been accumulated in the basket, the driver operates the cord 132 thereby swinging the hook 131 to disengage the eye 130 which permits the sections 116, 117, 118, 119 and 120 to close together, and at the same time move downwardly under gravity and under the action of the spring 158.

Shortly after this movement has co1n menced the member 133 engages with the end 18 1 of the rod 135, which through the connecting mechanism already described, operates the rod 1&4 to move the dog 1 18 permitting the rod 151 to move inwardly, and this in turn permits the cradle to turn on its pintles towards a discharging position in which the sheaves may be deposited on the ground in a vertical position.

Before this movement is completed however, the member 163 will engage the projecting end 164: of the rod 165, which will, through the mechanism already described, throw the pawl 170 into engagement with the continuously rotating disc 174 and cause the cam J to commence to turn.

Further movement of the roller 176 releases the cradle and permits the lever I to swing down, as already described. The roller 181 engaging the end 182 of the lever 183 will swing the lever or bale 97 backwardly which will permit the basket to drop substantially vertically.

The cam J continuing on its movement, the roller 185 thereof, will, through the mechanism already described including the lever 187, open the basket and permit the shock to disengage itself therefrom remaining on the ground.

l Vhen the lower pivoting points of the levers 93 and 9? are moved rearwardly after having been moved forwardly the stops 102 and. 103 will be swung into normal position. again and will finally become locked in position between the stops. After this takes place. the weight of the cradle will swing the lever rearwardly through the lever 97 carrying the member I rearwardly. After the shock has left the basket, the basket is, ret .rned to its normal position by motion of the cam acting on the roller 176 as. above described.

Any excess movement of the cradle is prevented by means of a flexible cord or cable 208 extending from the frame to the cradle.

On return movement of the cradle, the arms 84 and 85 are steadied by projecting arms 210 and 211 on the frame. The arms 210 and 211 are flexible and secured at one end to the main frame.

It will be seen that during the foregoing operation, the shock of sheaves is first compressed by the closing of the sections of the basket on them. The basket with its cradle is then turned to a vertical position and lowered, the doors closing the end of the basket being swung apart to permit the shock to be deposited on the ground. The basket and shock is thus lowered so that it will drop in a substantially vertical line and after the shock drops on the ground the basket moving backwardly remains with it momentarily until it is opened thereby giving proper form to the shock. The downward movement of the cone-shaped basket 1:.

will cause a pressure to be exerted on the shock which will serve to'press the sheaves together into a firm and proper shock.

After the shock has been deposited on the ground, the basket is opened and gradually raised and finally turned toward the horizontal and open position ready to receive the sheaves to form another shock. To relieve a portion of the weight of the basket and other mechanism, I provide a rope or cable 212 extending over a pulley 213 on the upright 21 1 having its opposite extremities connected by springs 215 and 216. It will be observed that the parts of the lever 1 are on opposite sides of the upright member 21 1 whereby the mechanism carried by the lever will counterbalance each other on opposite sides.

Retrograde movement of the cam J with respect to the roller 17 6, when the end movement of the cam is reached is prevented by a spring dog 217 on the cam which is pressed outwardly against a pin 218 by a spring 219 and is V-shaped and forms a ratchet for the roller 176, the roller being free to ride over the projecting end of the dog in one direction but not in the other.

Operation of the transferring mechanism during discharge of the shock is prevented by the end 63 of the lever 62 which becomes disengaged from the lever 93 against which it bears, thus permitting the lever 59 to turn under action of the spring 60, turning the end 5'? which moves the hook-shaped end 56 of the rod 43 laterally, disengaging it from the end and thus rendering inoperative the trip mechanism which would be normally operated by the means previously described, whenever a sheaf is discharged from the binder.

If the binder should discharge more than one sheaf during the time the shock forming mechanism is discharging. the additional sheaf will remain in the basket or transferring member and will be transferred with the next sheaf to the basket or shock formingmechanism when in proper position.

It will also be seen that by adjusting the relative length of the rod and shape of the cam, the tiltin motion of the basket could lei iii

be enlarged, increased, or eliminated as desired to suit the cha 'acter of crop or conditions of operation.

It will be observed that the mechanism above described causes the shock carrying basket to be raised slightly immediately after dropping to the'lowermost position and during opening of the basket, whereby the basket will be clear of the ground when opened and during withdrawal from the shock, this action being caused to take place by the shape of the cam J.

In order to prevent the grain'slipping lengthwise of the basket, a plurality of projections 220 are formed on both the transferrln basket and the shock formin basket.

The clutch mechanism is simple and efiective, composed of few parts all Well adapted to perform the functions required of them.

it will be observed that owing to the manner in which the collapsible basket is formed it automatically adjusts itself to different sized sheaves including short and long sheaves, the basket being formed with overlapping sections and being originally coneshaped and closing in from the top will enable the parts of the basket to automatically adjust themselves to suit the character of grain of Whichthe shock is to be formed.
